But Hillary Clinton's campaign is presenting the recent endorsement of Los Angeles mayor Antonio Villaraigosa to make a broader case for her strength amongst Latino voters.

In an e-mail that just went out to supporters, Clinton's top pollster, Mark Penn, argues that the number of Latino voters is increasing nationwide to about 7 percent of the electorate, and that Clinton enjoys about 60 percent of their support.

The release gives a state-by-state breakdown of where Clinton has the most strength with Latino voters, and, as Clinton often does on the campaign trail, mentions campaign manager Patti Solis-Doyle as evidence of her commitment to them.

Here's the email:

RE: Hillary Clinton's support among Latino voters

Today's key endorsement from Los Angeles Mayor Antonio Villaraigosa is proof that the Clinton Campaign's focus and strategy to win the Latino vote continues to grow stronger. Mayor Villaraigosa is one of America's great mayors and a dynamic national leader, who will play a key role in the campaign, advising on a range of policy issues that he focuses on every day as the mayor of America's second-largest city.

Hillary Clinton has a significant lead with Latino voters across the board and they will play a pivotal role in Nevada, and in many key Feb 5th states - they are critical in California, Texas, Florida, New York and New Jersey - and contribute to her lead in those states and other smaller states as well. They have been growing in Democratic support, and in the general election, they have steadily grown in importance. Latino voters have great respect for Senator Clinton. They have risen from 2% of the electorate in 1992 to what is likely to be about 7% in 2008. In the 2004 presidential election, an estimated 82% turned out to vote. Along with women, Hispanics are one of her most supportive and most important support groups. While George Bush captured about 40% of the Latino vote, Hillary is poised to reclaim the Latino vote that Democrats lost in 2004.

4. Hillary's Record

Hillary Clinton understands the challenges Latino voters face and for thirty-five years she's worked to solve them. While in law school Hillary researched the education and health of migrant children and after law school, she turned down lucrative jobs to work for the Children's Defense Fund because she wanted to make sure every child would grow up being nurtured and protected. She championed a bill that gave millions of uninsured children health insurance. She has been fighting to raise the minimum wage. And she has remained committed to providing more qualified teachers, better daycare, and college mentoring to help our children succeed. Just last week, Hillary Clinton proposed expanding pre-kindergarten classes to serve all of America's 4-year-olds today, providing them with a high-quality early education that studies show leads to higher achievement, graduation rates and higher-earning careers. Proposals such as these particularly benefit Latino families -- in 2005, twenty two percent of children under the age of five were Latino.

Hillary Clinton strongly supports comprehensive immigration reform, family reunification, and the DREAM Act, which would enable students who are the children of non-citizens to pursue higher education without residency restrictions. She remains committed to addressing healthcare disparities, sponsoring legislation which allows legal immigrant children and pregnant women to obtain Medicaid and SCHIP.

Hillary Clinton recently introduced an amendment to remove barriers to reunification for the nuclear families of lawful permanent residents. The amendment would reclassify the spouses and minor children of lawful permanent immigrants as "immediate relatives," thereby exempting them from the visa caps. She did this because Hillary Clinton knows, "The United States is a country built by immigrants, but our laws are tearing legal immigrant families apart."

Hillary Clinton's support of sensible immigration reform, including earned citizenship and family reunification has helped her win strong support in the Latino community. Her support for universal health care, a higher minimum wage, universal pre-kindergarten and full funding for Head Start also help explain why she is so popular among Latinos.

5. Campaign

Hillary Clinton is showing her commitment to the Hispanic community and eagerness to hear from them. She has staffed the highest levels of her campaign with highly qualified Hispanics, starting with her campaign manager Patti Solis-Doyle - the first Latina ever to lead a presidential campaign.
